Read Device Identifier

The Read Device Identifier command instructs the device to output manufacturer code,

device identifier code, block-lock status, OTP Register data, or Read Configuration

issuing the Read Device Identifier command). Table 7, “Device Identifier Information”

on page 21 and Table 8, “Device ID codes” on page 21 show the address offsets and

data values for this device.

7.4

Read CFI

The Read CFI command instructs the device to output Common Flash Interface data

when read. See Section 6.1, “Device Command Codes” on page 16 for detail on issuing

the CFI Query command. Section A.1, “Common Flash Interface” on page 60 shows CFI

information and address offsets within the CFI database.
